 For target_field `watch-time`, target_field_value must be an integer
 value indicating the media progress time in seconds between (0, 86400]
 (excludes 0, includes 86400) (e.g., 90).
 For target_field `watch-percentage`, the target_field_value must be a
 valid float value between (0, 1.0] (excludes 0, includes 1.0) (e.g.,

 is frequency of training - this can be used to determine when to train
 engine in order to control cost. If not specified: the default value for
 `CreateEngine` method is `TRAINING`. The default value for
 `UpdateEngine` method is to keep the state the same as before.
